Late spring seems to have brought out the confrontationist in me.First it was Donald Norman and his assertion that simplicity on the web is overrated. Now it's Lyle Kantrovich and his rail against sitemaps in Sitemaps are Stupid (Guides are Good).Guides may very well provide distinct advantages over sitemaps. But calling them "stupid"? That seems incredibly harsh.Once again (at least to my eyes), the author is not taking into account the special-needs user . In many cases, these text-only representations of site structure may be the only way for certain user types to navigate with any degree of confidence -- for example, those who rely on screen readers, or those who have trouble with sites containing high levels of rich media (navigation in Flash, etc.) Sitemaps may indeed be fairly useless for "normal" people, who have good vision and/or a reasonable degree of computer literacy, but their presence on web sites seems to me to be a very small price to pay to ensure that the content is accessible to as many people as possible.

A nice article by Jessica S. Ancker notes why you should not rely on the Flesch-Kincaid scale (or any other scale) for determining the readability of text, on-screen or otherwise.To get a quick idea of why, check out the following passages and guess which one was determined to be easier to read by Flesch-Kincaid:--------

It was to be the highlight of Year 1 at my position.Seven one-on-one sessions with actual customers over a 3-day period, testing an intermediate iteration of my company's major new product release. Participants had been screened, incentives had been procured, facilities had been reserved and the test plan had been finalized. Everything was ready to go.Except, as it turns out, the product itself. Unforeseen development issues pushed back deadlines and left me with a prototype that did not allow for completing any meaningful tasks.Nobody to blame but myself, of course. I should have had the foresight to (a) insist on a "frozen" set of functionalities in accordance with the particulars of the test plan, and (b) allow for a minimum 2-week buffer between the promised delivery date and the actual testing. Instead, I was too eager to (a) believe that everything would fall into place as scheduled, and (b) put my new Morae software to practical use. In the process, I probably did my role within the company a bit of disservice.So what then to do?If my UX studies taught me anything, it's that you never turn down an opportunity to glean direct user input. The opportunities, by and large, are just too few and far between. Fortunately, I was only a few weeks removed from completing a fantastic master's level class on field research methods taught by Meena Kothandaraman, and I drew on much of what she had to say to draw up an alternate plan.Targeting three product design issues that were never quite addressed to my satisfaction, I turned what were supposed to be usability testing sessions into three-part user research sessions, consisting of the following techniques:

a contextual interview, to get insights into the likelihood of acceptance for a proposed functionality;

conceptual drawing, to discern patterns of experience and preference for the design of a field mapping tool; and

a card sort, to provide an organization solution for a group of functionality options within the product.

While the allotted time did not allow for full investigation into the issues, I got enough to go back to the project managers with preliminary data to be used to guide design decisions for the product's next dot version (the results of the card sort were particularly revealing). From a personal standpoint, I got to practice a few techniques with which I had very little experience.

Does the "Keep It Simple, Stupid" principle have it wrong?Could be, according to Don Norman, who's been cited numerous times here. His recent article, Simplicity Is Highly Overrated, seems to argue that the K-I-S-S principle should be replaced by something like the K-I-S-B-M-S-I-L-C-E-S-T-I-F-B-A-M-P-D-S Principle:

"Keep It Simple But Make Sure It Looks Complicated Enough So That I'll Feel Better About My Purchasing Decision, Stupid"

The point he wishes to emphasize (located in the addendum) is that "people are not willing to pay for a system that looks simpler, because it looks less capable." In other words, systems that look more complicated seem capable of doing more, which positively effects the desire to purchase.

"When users don't understand the advantages of each feature, such as when a user is buying her first digital camera, they are much more likely to avoid making a trade-off by choosing the feature-laden product . . . When users choose a feature-laden product, they may not be exhibiting a desire for complexity. Instead, users are anxious about predicting their future needs. Norman states it plainly: 'the truth is, simplicity does not sell'."

For UCD practitioners, these could be interpreted as "fightin' words" that run contrary to the principles that guide our profession.

What strikes me, though, is that neither Norman (in his essay) nor Porter (in his commentary) explicitly takes into account the age factor, which will kick in very soon when the aging boomers predominate the purchasing market.

Given the advances of the last few decades, the coming generation of seniors is probably less likely to be intimidated by new technologies. But to what degree will this be offset the various degenerations that inherently accompany aging (cognitive processing, decision-making, motor skills, peripheral vision, etc.)? Does the visibility of extra controls, or an overall high-tech look, carry any weight at all when it comes to forking over their hard-earned retirement allowances?

For these users, simplicity may indeed sell.

I think of my parents (both in their upper 60s), who, when shopping for a new appliance or gizmo, repeat the phrase "All I want to be able to do is . . ." an awful lot and are turned off by anything that they perceive as being beyond their ability to operate. What's more, they have very little motivation to learn, especially if "all I want to do is (watch TV, wash clothes, whatever)." Are they really unique to the coming generation of seniors?

To his great credit, Norman wants only for his essay to be understood, and the addendum does a good job of clarifying his intended point. However, sweeping statements such as those made in the essay cannot be fully understood until all relevant issues are included. In this respect, my humble opinion is that Norman has come up short.

With the coming of the new year, I promised myself that this space would not fall victim to expiration -- that is, I would commit to posting frequently. Not because I expect to become UCD's answer to AriannaHuffington, but because amateur writers can be very much like infants, in that they tend to thrive on routine and regularity. I reasoned that if I could commit to posting at least once a week, I would eventually not need to remindmyself to post at least once a week. (Sharp moviegoers will notice that I'm borrowing here almost verbatim from Sleepless in Seattle, so disclosure is warranted.)

So here it is, almost April, and I've not posted in more than a month. (There are reasons, as you will undoubtedly see in this space as spring unfolds, but I can't use it as an excuse.) I'm also far, far behind in the monitoring of my industry-related RSS feeds. Leave it to the powers that be to send me a loud-and-clear wake-up call, in the form of Linda Bustos' recent article, The 10 Sins of Blog Usability.I'm not sure whether or not the title represents a mixed metaphor -- there are 7 Deadly Sins, and 10 Commandments (I suppose it depends on the way they are worded.) In any event, I am clearly in violation of #8 -- Inconsistent Posting:

Now that you have a loyal fan base who are notified of every newpost, don’t disappoint them with time lags between posts. Pick a postingschedule that’s realistic for your time schedule and stick to it. If you can’tthink of anything to post about, blog about someone else’s post related to yourtopic and include a link back to that post . . .

(You'll note that not only does she wake me out of my self-imposed slumber, but she gives me the means of rectifying it.)Fortunately, this space appears to hold up fairly well against Bustos' criteria -- comments are moderated, there is no advertising to "get in the way" of the message, there's no mixing of subject matter (no matter how much I might want to brag about my daughters), the pages are easy to read (dark text on a light background), and references to previous posts are link-enabled. My two failings against the list are (a) not having a search functionality and (b) an awkward means of subscribing via RSS feed, but until I noticed huge increases in my Site Meter reports, I'm going to let those pass.What I can't afford to let pass, regardless of the size of my "loyal fan base," is old #8. My hope is that if I make my intentions public here, I'll hold myself more accountable -- or, to carry the analogy further, I'll have given myself the leeway to "go forth and sin no more."Your kind indulgence is greatly appreciated.

The most interesting thing I came across in the study was the degree to which people equated the concept of an RSS feed with that of a "ticker" at the bottom of a TV screen, with stock prices zooming by from right to left. If this is representative of a larger portion of the population, no wonder RSS hasn't caught on -- where's the value in being forced to stare at the bottom of a browser window all day?

The findings and recommendations for content providers are as follows:

Finding: Although users continue to employ “hunting” methods most often when checking for added or updated content, certain “gathering” methods (such as email notifications & alerts) are used frequently and provide a sense of value for users (saving time and effort, better organization of important information, serving as a reminder for busy people to "check in" with a site).Recommendation: Companies investing in RSS feeds and technology should find ways to incorporate the concept “invisibly” (i.e., deliver the benefits without any learning or undue effort required on the part of the user). Read Gossnickle et al's .pdf, RSS – Crossing into the Mainstream, for more information (Acrobat Reader required).

Finding: There is not a high degree of awareness or understanding of the terms and visual targets used to represent “gathering” methods on websites (see Part 1); for those that are noticed, there remains a strong association with delivery via email.Recommendation: Aside from direct links to personalized “start” pages (“My Yahoo!", etc.), content providers should devise and use a single, more intuitive means of conveying the RSS feed concept. (“XML” is highly misunderstood and should not be considered.) In addition, differentiation from delivery via email should be emphasized and explained simplistically.

Finding: Understanding of the RSS concept (as a “gathering” method) can be improved by exposure to a well-written description; however, understanding of the implementation/delivery of information continues to be a problem.Recommendation: Short-term, companies need to make the required use of an RSS reader/aggregator more understandable to the general public, in a positive way that eliminates any association with email notifications or content “crawls” within browser windows. Descriptions and definitions of RSS require clear, plain English -- technical-sounding phrases such as "XML-based format" and "aggregating Web content" are big no-no's).

Finding: The already recognized benefits of “gathering” methods (time savings, organization of information, etc.) are enough to encourage further investigation of using RSS feeds. Concerns about information overload, management, privacy and technological conflict (can it lead to viruses and/or spam, etc.) can discourage investigation.

Recommendation: Further promote the “gathering” concept within all references to RSS on websites, while directly addressing the areas of concern as noted.

My sincerest thanks for those who took time out of their busy schedules to speak with me. Please leave a comment if you'd like more details about the study.

If you check in frequently with a news, sports or blog site, chances are you've seen them and wondered what they mean:

The Internet world remains largely one of “hunters” rather than “gatherers” – that is, we tend to actively seek out additions and changes on web sites, rather than having them come to us. Think about your favorite news website -- if you want to see what's new, you probably access the site by typing the URL into the browser's address window, selecting the URL from the address drop-down menu, or choosing it from your Favorites menu, then browse the pages "hunting" for the new, updated, or changed content.

Compare that to signing up to receive an "alert" or notification about updated content (new headlines, shopping deals you might be interested in, etc.) that comes to your email inbox. In this instance, you'd be "gathering" the new, updated or changed content before acting on it.

RSS (Really Simple Syndication) is the next step in this "gathering" concept, and it offers enormous opportunities for Internet users (and content providers as well, but that's another story). Its major selling point for Internet users is in saving significant time and reduced effort, by driving the content that matters most to a central viewing location automatically.
